A deluge of eggs, perhaps 2,000 in
all, issuesfrom a gravidfemale in a
jar (left) outside the laboratoryat
PalmerStation. A screen prevents the
motherfrom eating her own eggs.
A female stores the male's sperm
and releases it to fertilize her eggs,
which appearas small bubbles in her
feeding basket (below). Colleagues of
the author discovered that a female
can produce many sets of eggs
totaling more than 20,000-during
the summer spawning season.
Krill larvae emerge from their
shells (bottom). In nature this occurs
at depths of several hundred meters,
where, safe from predators,the larvae
subsist on yolky materials.
